3. Talk about your future

People in serious relationships plan plural futures. They say things like "Once we save up enough money…" or "Someday we would really like to…"

Therefore, one way to indicate that you aren't interested in a serious relationship is to talk about your fabulous independent future. Mention that you've always wanted to move to a larger city or spend a couple years working in Europe. Don't include her in your future fantasies. Don't mention marriage or kids. Talking about your future is one of our top 10 ways to take it down a notch because it communicates that she's not part of your long-term plan — at least not yet.
